en.Wedoany.com Reported - A pilot project has been launched in Chile's Coquimbo region to inject green hydrogen into the natural gas distribution network, supplying energy to homes in La Serena and Coquimbo. Operated by gas distributor GasValpo, the project currently blends 10% green hydrogen with 90% natural gas, with plans to increase the blend to 15% by 2026 and a long-term target of 20%. Regional authorities describe this initiative as South America's first residential hydrogen blending project.

The project initially started with a 3.5% hydrogen blend, which increased to 5% after the installation of on-site electrolyzers producing hydrogen from renewable energy. It is estimated that when the blend reaches 20%, this green hydrogen blending project could reduce approximately 340 tons of carbon dioxide emissions annually.

The Faculty of Engineering at the University of La Serena is monitoring the system's material compatibility with the existing natural gas network and household appliances, as well as combustion quality and emission performance. GasValpo reports that the hydrogen blend has no visible impact on end-users.

Regional authorities stated that this pilot is a crucial step in Chile's broader green hydrogen strategy. Leveraging the renewable energy potential of the Coquimbo region, it helps reduce dependence on imported fossil natural gas while stabilizing heating fuel costs.
